A train is traveling at 60 mph. If the rate of speed increases 4 mph each hour, how long will it be before the ship is traveling at a rate of 80 mph?
It depends on how fast you are traveling. If you are traveling at the speed of 60 miles per hour, you would divide 3300/60 to get 55, as in 55 hours. Distance/speed=Time or Time*Speed=Distance
Impossible to answer without knowing an average speed. Big difference between traveling by car and traveling by jet plane.
That depends on the speed at which one is traveling.

We call them ultra sonic planes. There is a sonic boom it is traveling when this speed.
Assuming that both vehicles were in the center of a straight road, and neither vehicles driver hit the brakes, the closure rate would be 100 mph.
There is addition of the speed.
Some vehicles mount a speed sensor on the drive shaft, to see how fast the vehicle is traveling. Not all vehicles use this kind of sensor.
He recognized that the way Dee Futz agree wit me we see the universe depends on our reference point and on whether we are traveling at a speed approaching the speed of light. Being in a deep gravity well can have a similar effect as that of traveling at relativistic speeds. Einstein was a kind and gentle and cool man.
cruising speed
You can be accelerating and traveling at a constant speed if you change directions.
-- If you are not attached to either of those light waves, then you see each of them moving at the speed of 'c'. -- If you are attached to either one and traveling with it, then you see the other one approaching you at the speed of 'c'.
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
The speed limit would be irrelevant, because the only practical vehicle which could travel at such speeds would be some sort of jet aircraft. You'd be traveling at a speed of 510 mph, which the only land vehicles capable of achieving such speeds are jet or rocket propelled vehicles designed specifically to challenge the land speed record.
